which speakers?

obviously component speakers are better than coax but they are more expensive.

should i look at getting component speaks even though i'm not too keen on the idea of cuttin up my car to mount the tweets? plus the fact that i don't have a clue how to wire them. what is the little box looking thing that comes with them as well?

as far as brands go, i've heard a lot of talk about mb quart on here and other forums. they are a little pricy but if the sound is good then i guess its worth it. i was originally looking at infinity or alpines. any suggestions?

i always believed coaxial are the 2 way 3 way and 4 way type speaker(s) where the tweeter is with the woofer where as component have a sepereate tweeter and a seperate woofer. if this is incorrect PLEASE someone correct me

you are correct, although a coax can have five channels too (some of the new pioneers are five channel), for the fronts I would really recommend getitng components, once you hear them you will be glad you did.  As far as the box yes it is a crossover (one of the benefits of a component), and yes you wire from the deck to the crossover and the crossover will split it into different signals for the midrange and tweet, its very easy to wire.  Some of the benefits of the component is you will always get a much higher treble out of them, the tweeters that come with components are normally just completely out of comparison to those found in coaxes; you wont have to worry about the sub (midbass) that is placed behind the tweet on a coax distorting the sound of the tweeter when you have components.  All in all every time I have sold/installed a set of nice components to someone they have always been completely happy with their choice, even if it costs a little more.  Some of the brands I would recommend would be boston acoustics, focal, mb quart, I hear good things about the alpine type r components, and Ive had really good luck with the fosgate ones (very good sound for your money).

what would you recommend getting in the rear. i'm going to be putting 2 12's in but i want some 6x9's as well. i've seen a few 6x9 components, u ever seen these before? if i went with mb quart for the front what would good rears be?

how do you wire up the crossover and where do you put it?

I recomend you GO LISTEN to some speakers and buy whatever sounds good to you. 

A good coaxial can sound every bit as good as a component set.  Indeed, some coax sets sound much better than some component sets.  Many coaxials (like Infinity Kappa) use the exact same speakers as do the components in their product line.  Components give you more flexibility in mounting and IN GENERAL can give you better quality parts, but not always.  Install what sounds best to you.
